3-1. Introduction
Aurora Four lights consist of several modules
containing LEDs (light emitting diodes) and optical
colorcorrectivereectors.Eachlightheadfeatures
independent focus capability allowing the user
to adjust the illumination parameters. The light
intensityisadjustableatve(5)levelsandacolor
temperatureof4100Kor4500Kcreatingtheinnite
capability to adapt to di󰀨erent situations.  LEDs
o󰀨erlowheatradiationandincreasedillumination
longevity.
Light model combinations are available with one,
two, or three lightheads providing high illumination of
theoperatingeldatvaryingangles.Combinations
of vertical positioning and multiple rotational
capabilities allow the single, dual, or triple lighthead
models virtually limitless positioning within a 13
foot (4 m) diameter area (triple-lighthead models).
The xtures can have an optional camera on a
lighthead or camerahead. The camera system is
integrated with a camera control unit (CCU) and
described in greater detail in Section 4.
Standardxturesaresinglepointceilingmounted
withaninnitelycontinuous360°rotationcapability
at the ceiling mount end of the radial support arm
(Figure 1). The balance mechanism, which is
attached to the radial arm by a vertical support
tube,providesthelightheadanadditionalinnitely
continuous 360° rotation point. The balance
mechanism is an enclosed spring tension system.
This allows vertical movement of the lighthead while
maintaining the lighthead position without drifting.
Theyokeprovidesadditionalinnitelycontinuous
rotation points for lighthead pitch and roll.
Variable length arm and Variable length hub
(AUA_H) models are available for custom
applications.Thesextureshave340°(maximum)
rotation at the ceiling mount instead of 360°.
AllAuroraFourceilingmountedlightxtureshave
a lighthead vertical travel capability of 110°.

3-2. Features
Lightheads are available in two (2) sizes. The
smallerAUA5hasve(5)LEDpods.Thelarger
AUA7 has seven (7) LED pods. Multiple lighthead
xtures will typically have one (1) larger AUA7
lighthead as the primary light source with the
smaller AUA5 lighthead(s) serving as satellite(s)
or secondary light source(s).
AUA5 and AUA7 lightheads are available in
camerareadycongurationsalongwiththeVCA
camerahead.
a. Standard Lighthead (AUA5 & AUA7)
Positioning handles are located on the side for
non-sterile personnel to position the lighthead
(Figure 2).

Figure 2. Standard Lighthead
An adjustable focus mechanism optimizes the light
output by superimposing the light beams from all
of the pods into a single spot. A focus knob is
located on the side of the lighthead for non-sterile
personnel to adjust or focus this spot based on the
lighthead position.
All of the standard lightheads also have a sterilizable
focus/positioning handle that is removable and
sterilizable. The handle allows focus control,
lighthead positioning, and intensity adjustment.
Thisallowsallnaladjustmentsorchangestobe
precisely controlled by the surgeon.
A button is positioned on the end of the handle to
provideintensitycontroloftheentirexture.All
of the lightheads connected to a wall control are
controlled by a single handle.
• Pressing the button and quickly releasing
it will cause the intensity control to cycle to the
next lower position.
• Pressing the button again will cycle the
intensity control through all levels. When the
lowest intensity is reached, the control will next
cycle to full intensity.
b. Camera Ready Lighthead (AUA5TV &
AUA7TV and Camerahead (VCA)
Like the standard lighthead, a camera ready
lighthead also includes the positioning handles and
side focus knob for non-sterile personnel (Figure
3). The camerahead has only a positioning handle
(Figure 3).

The handle for the camerahead can be sterilized
before use. If it needs to be used in a sterile
condition, do not allow contact by non-sterile
personnel.
The camera ready lighthead is designed to accept
a Precision HD camera in place of the sterilizable
focus/positioning handle. A sterilizable camera
cover installs over the camera in both the camera
ready lighthead and the camerahead to permit
sterile focus control and lighthead positioning
adjustments by the surgeon.
See Section 4 for additional information on the
installation and use of the Precision HD camera
system.
